There is a very special easter egg in Halo: Reach on "The Package", that is almost impossible to find unless someone told you about it. It's going to require a second player at minimum to help you, as well as having to play on Legendary. If you can do it, you will get the holy grail of easter eggs in the game: a fan tribute room built by Bungie for the community! In this video, the guys over at Achievement Hunter show you how to activate the room, and also geek out over seeing themselves in the room as well!
